Home remedies for mole control are numerous. Pouring any of the following readily available home products into the mole tunnels is said to encourage moles to seek other habitats. Pickle juice, broken glass, red pepper, bleach, mothballs, rose branches, or human hairballs is said to be successful for controlling mole populations. Vibrators and ultrasonic devices are sold in stores for the purpose of getting rid of moles.
Cats are a natural predator of moles. Pour used cat litter into the run or mole hill to get rid of moles. This must be repeated until the moles have disappeared.
